1 Claim. 1

This invention relates to safety snap.

It is an object of the present invention to provide a safety snap whichis so constructed to fit under a piece of clothing or cloth and with acooperating element which will contain the first snap element and thecloth, whereby to secure the two elements and the cloth portionstogether.

It is another object to provide a safety snap device for use on clothingand to eliminate the use of the standard safety pin which has a pointedend.

Other objects of the invention are to provide a safety snap arrangementadapted to contain clothing or cloth which is of simple construction,inexpensive to manufacture, has a minimum number of parts, and iscompact, easy to operate and convenient to use. I

For a better understanding of the invention, reference may be had to thefollowing detailed description taken in connection with the accompanyingdrawing, in which: v

Fig. 1 is a collective and perspective view of the two elements formingthe safety snap designed according to one form of the invention.

Fig. 2 is a sectional view taken on line 2--2 of Fig. 1 with the partsin assembled relationship.

Fig. 3 is a collective view of the several parts of the fastenerseparated from one another and shown in perspective, the spring elementsbeing separated and released from the projections of the one part.

Fig. 4 is a top planned view of the one part containing the springelements.

Fig. 5 is an enlarged vertical sectional view of a safety snap accordingto another form of the invention, wherein projections of thesprings areprovided to effect the release of the parts.

Fig. 6 is a fragmentary perspective view of the spring assembly partwith a section thereof removed to show the spring with its projection infull perspective.

Referring now particularly to Figs. 1, 2, 3 and 4, ll! represents one ofthe snap elements which has a central projection or protrusion ll overwhich the cloth is placed. This element may have a plurality of smallholes l2 for the purpose of attaching it to a garment by means of thepassage of thread through the holes and to the garment material.

A second element I3 is formed of an assembly of a backing part l4,opposing springs l5 and I6, and a cover part [1. The backing part has anupstanding peripherial flange I 8 and a central opening l9. Also, struckupwardly from within the part are a plurality of struck up portions ortabs 2| arranged in pairs and each pair adapted to receive and retaineither a spring IE or a spring IS. The spring l5 has an intermediateportion l5 and two end portions |5a and I51) formed of a reverse curvefrom the intermediate portion l5. The spring element It has anintermediate portion I6 and reverse curved end portions l to and lb.These spring elements are fitted into the part I l outwardly of thestruck in tabs in the manner asshown in Fig. 4. The intermediateportions will extend inwardly beyond the edge of the hole Hi. i a

The part I! of the assembly l3 has tabs 22 angularly spaced from oneanother and these tabs extend about the flange I8 of the part or memberM. These tabs will lock the parts 14 and I! together. This member I! hasa hole 23 equal in size to, the hole I 9 of the member 14. Small holes24' are provided in the part I! by which the assembly can be fixed bymeans of.

thread to a garment or cloth material.

' It will be seen that the springs are located in the base part It andare centered in position by the struck portions 2| and the flange l8.Part I! is placed over the part I l and held in assembled position bybending the tabs.

The head of the member I 0 is pushed into the openings 19 and 23 of therespective parts l4 and i1 and will press outwardly the springs l5 and I6 and the intermediate portions l5 and Hi of the respective springs willretain the head ll of the member Hi. When the pressure on the spring isreleased the springs return to their original positions. As the head I lis pulled from the assembly, a similar deflection of the springs l5 andI6 is made. The holes [9 and 23 are sumciently large so that a cloth canbe projected through the same by means of the head II.

The arrangement is particularly adaptable for connecting together theends of diapers and similar cloth material. The arrangement will getaway from the safety pins which are ordinarily used on babies diapersand provide a more safe means.

Referring now more particularly to Figs. 5 and 6, there is shown anarrangement wherein the springs can be levered in such a manner as to beeasily released from the head and without having to force the parts ofthe fastener assembly from each other. According to this form of theinvention there is provided a body member 25 having a head 26 with asharp shoulder 26'. The assembly, including a part 28 and a part 29,held together by tabs29' and which respectively have openings 3| and 32to receive the head 25. These openings 3| and 32 are sufiiciently largeto receive a cloth with the heading 26.

Special spring elements 33 and 34 are used. These spring elements areheld by projections 35 struck inwardly from the flanged member 28. Eachspring element has an intermediate portion and reverse curve endportions which are attached to the tabs 35. On the intermediate portionof each spring element is ahandle projection 35 which has an enlargedend 36' and which can be levered to pull in the intermediate portion ofthe spring and to release the head 26. The handle projection. 36-extends through diametrically-spaced holes 3? and 38 in the part 29 andcan pivot against the sides of the holes. By grasping the twoprojections 36 which extend outwardly from the springs 33- and 34, theintermediate portions of the springs will be levered from the shoulder26. This will release the head 2'8 and permit the members to bedisengaged from one another; As soon as the handle projections 35 are"released, the springs will assume their original shapes and prepare thesame for the next insertion of the head 26; It will thus be apparentthat the 'parts can be more quickly severed from one another by a simplesqueezing together of the handle projections' 36.

Whilevarious changes may be made in the detail construction, it shall beunderstood that such changes shall be within the spirit and scope of theappended claim.

We claim:

A- snapfastener assembly comprising a body member having anenlarged-central head projecting' therefrom, said central head having aperipheral shoulder, an assembly adapted to receive' said head andcomprising two parts fastened together, one of said parts having inward-40 ly-extending; projections arranged in pairs spaced apart from oneanother, opposing spring elements, each of said spring elements having abowed intermediate portion adapted to engage the peripheral shoulder ofthe central head of the body member and reversely bowed end portions,said pairs of projections of the one part receiving the reversely bentend portions of the respective spring elements, said body member furtherhaving a peripheral flange and the reversely'bowedend portions of thespring elements being confined between the flangefland the projections,the other part being fastened to the one part and confining said springelements therebetween, said assembly parts having registered centralopenings for receiving the head of the body member, the intermediateportions of -therespecti-ve spring elements extending inward- 151' ofthe periphery of the registered central opening, said one part havingdiametrically spaced holes disposed respectively at the opposite sidesof the central opening of the other part and each of said springelements having forwardly-extending. projections extending. respectivelythroughsaidfdiametricallyspaced holes and operable whenr leveredradial-1y inwardly on the sides of said holes to release the springsfromtheperipheral shoulder of the. central head whereby upon squeezingtogether. said handle. projections the assembly may be quicklyand easilyseparated from bodymember.
